We only guarantee the compatibility if the part number is an exact match to the one that is being replaced.OFFER We do not typically take offers on our items. In the rare instance that we receive an offer, we will review it and will only respond to offers that will be accepted. If you don't hear back, your offer is not acceptable. Please do not submit an offer or multiple offers on the hope one may get accepted. ORDERS Our system will combine order automatically if they fall within a set of guidelines. If a replacement is available, it will be offered through the return system. This product contains a chemical known to the State of California to cause cancer. OptiPlex 3040 / 5040 / 7040 SFF.
